Induction heating coupler and annealer

An induction heating device includes a handle having a hollow interior and two opposite ends, a wrist connected to one end of the handle, a U-shaped pole piece having- two spaced apart ends, a tank circuit including an induction coil wrapped around the pole piece and a capacitor connected to the induction coil, a head connected to the wrist and including a housing for receiving the U-shaped pole piece, the two spaced apart ends of the pole piece extending outwardly beyond the housing, and a power source connected to the tank circuit. When the tank circuit is energized and a susceptor is placed in juxtaposition to the ends of the U-shaped pole piece, the susceptor is heated by induction heating due to a magnetic flux passing between the two ends of the pole piece

Dynamics Analysis of Ground Contact Pressure of English Pointer Dogs

Abstract. In this study force sensing resistors were used to determine the pressure on the central area of each of the weight bearing pads of the fore and hind paws of dogs at the walk. Six adult normal healthy English Pointer dogs were used in this project. Pressure data were collected by affixing a force sensing resistor to the central area of the ground contact surface of each weight bearing paw pad of the right fore and hind limbs. Pressure signal data from stance phase during walking were analyzed. Within paw pads, the pressure graphs were consistent in form and magnitude. Within paws, there were significant pressure differences among pads on both fore and hind limbs. The coefficient of restitution, the embedding dimension, and the Lyapunov exponents were calculated. The ability to measure and analyze pressure on individual paw pads provides insight into soft tissue stresses on the palmar/plantar surface of the paw. Pressure at a wound site on the pads has a detrimental effect on wound healing and a better understanding these stresses will be of benefit when suturing and bandaging pad wounds. Such information is especially important in athletic and working dogs, e.g. search and rescue dogs

Magnetised quark nuggets in the atmosphere

A search for magnetised quark nuggets (MQN) is reported using acoustic signals from hydrophones placed in the Great Salt Lake (GSL) in the USA. No events satisfying the expected signature were seen. This observation allows limits to be set on the flux of MQNs penetrating the Earth’s atmosphere and depositing energy in the GSL. The expected signature of the events was ​derived from pressure pulses caused by high-explosive cords between the lake surface and bottom at various locations in the GSL. The limits obtained from this search are compared with those obtained from previous searches and are compared to models for the formation of MQNs
